Thi s'linvention relates to devices for cleaningthe tubes of boilers, economize rs and the like, c'ommonlyknown as soot-cleaners, and

aimsfto provide improvements therein. i

5 The invention-provides improvements in the type of soot cleaners where thevalves are I locatedcloseto the cleaner element, and both the valvesand elementare operated by,a sln gle operating means, as disclosed in the patent of Frederick WQLinaker, No. 1,413,601, grantedApril 25, 1922, to one of the present ap'y plicants.

' In the present improved construction, the opening andclosing of the valveis. automati- 'cally' effected, through the I'operationf of a j single means whichop'eratesboththe valve and the element, the entire structurebeing simple in construction, compact and reliable. The present invention provides aconstructlon 'for accomplishing the same general purpose as theinvention set forth and claimed in our application Serial No. 631,644, fiIed April' 12,]1923, but which is another means and which is simpler.

,An embodiment of the invention is illustrated in the accompanying drawingsgin which) Figure leis a longitudinal sectional view showing the head andso muchlofanlelement as is necessary to show the invention, the sec- ,tion being on line1 1, Fig. 2.

to F1 51s a sectional viewon the line 55 7 Referring to said drawings, numeral 10 des ignates the cleaner or blower element, which projectsfthrough the wall-11 of a furnace or the like, and which isprovided with aseries V ofjnozzles (not shown); through which; jets of steam are projected toperiform theclea n 'ing' of, soot from the boilertubes, in Well known'manner.

' x stam (or aha su m y suitable source is supplied through a pipe 15to ahead 17, which has a valve 19 therein for' cont rolling the flow of steam to andfrom the element 10,

, The element 10. has a turning connection with said head 17, as a stufiing-box connection 21, and is rotated by suitable means, as by means of a sprocket :wheel 23 fixed on said 'element, overwhichgsprocket Wheel an end- (not shown) is ordinarily is 'slidable to and from a positionopening and closing the orifice 33, for. which purpose suitable means 35 are provided within the head 17 and connecting with the element 10,

in such manner thatthe turning of said element 10 by its operating means 23 eiiects the 75 opening and closing of the parts of the valve 19. The means 35 includes an annularsurface 46 andarecess .48, aswill be described. The valve member 30 is conveniently pivoted to the valve seat 31, as by means of an eccentric pin 37 passing through said 'valve member and screwed into said. seat member '31. The valve member 30 has an arm or extension 40, which is conveniently forked to accommodate aroller 42, and which arm coacts with .a stop 44 on thehead 17 to turn said valve member to open position when the element 10'is turned in a counter-clockwise direction .(Fig. 2). In Fig, 3 the valve is shownin partly openposition, The roller 42 is adapted toride oversaidstop 44 after the valve has been opened, and beyond said stop 44 V the head 17 is. providedwith guiding means,

as the'inner wall 46'of the heath-for restrains 'ing said arm 40 to prevent it from moving. in v as v stop 50 againstwhich a projection 52 on said arm '40 is adapted to strike when the arm, on the return movement of the element 10, is moved over and beyond said stop 44. This stop 50, on the continuedniovement of the element 10 in a clockwise direction after the projection 52 makes contact .therewith,,actsto turn said arm 40 toturn the'valvemember 30 to a position closing said orifice 33, and thus to close said valve, and stop the How of steam to the element 10. As the projection 52 extends beyond the roller 42 on arm 40, a groove 54 is provided therefor in the'inner wall of the head 17. I a

A plate 56 is conveniently provided on seat member 31 between which and the said seat member the valve "properslides and is housed. This plate 56 is conveniently supported and held in spaced relation totheseat member, by means of posts 58, 59," having nuts '62 thereon for fastening said plate on said posts. Theposts 58 and 60also serve as stops for limiting the movement of said valve member 30 after it has been fully opened and fully closed, Opposite the orifice33, the plate 56 is preferably provided with a corresponding orifice 64. I f

a For the purpose of making. atight joint with the valve seat the valve member is provided with a recess or opening 66 within which is fitted a valve disk 68, of suitable material such as Monel metal, of somewhat greater diameter than the orifices 33 and 64,'and the disk 68is normally pressed toward Valve seat 31 by means of a spring 7 O'housed i in said recess 66and bearing against the back a so of said disk68.

* Our present'construction resembles that set forth, in our said application No. 631,644, in that the valve'is mountedinternally within a V chamber formed by the head which intervenes between the steamadmission pipe and the cleaner, element or blower tubeythe latter turning within said head. The general'op eration isthe same, that isto say, the element moves from an initial inactive position, turning in one direction through an are which may be varied according to location, and then backward to the initial position; in the inactive position the valve isclosed,andinthe initial-movement it is opened, being thereto its'inactive position, the valveis automatically closed. The present construction'dif-l fers from those set forth in said application in several respects; in the earlier constructions the valve consists in each'instance of two members, one of which is carried with the blower element, and the other has a limited'relative movement, being stationary dur ing the initial movement of the'blower element until the valve ports are opened, and thereupon the two members are locked to the gether sothat they both turn With'the blower element, the lock being released near the end of the return movement of the blower element,'and the relatively movable valve member striking a'stop which holds it stationary during the final movement of the blower ele-f ment,wherebythe respective valve ports are I closedp 'In the present construction, how ever, there is no lock uniting two valve members, but the valve proper or valve disk 68 slides relatively to'the-valve opening orseat 33, in the seat, member 31', which turns with V and to its inactive position. This arm is pivi otedeccentrically to the axis-of rotation of the blower element, and therefore eccentrically to the retaining member, which in the construction shown is the innerface 46 of the head, and which ispreferably concentric r with the said axis ofrotationfThe move ments of thearm, and consequently of the valve member, are accomplished by its en tering or leaving the vrecess 48, being performed by the opposite stops 50 andf44', and

afterpassing the latter, the arm (or its anti' friction roller-42) by traversing the concen tric retaining member '46, is by reason of its eccentric pivot 37 held inposition: to retain the valveopen'during theentire rotary movement of the blower element. A desirably quick movement is given to the valve proper] 68, since its motion is in the contrary direction to that of the valve seat which is turningtwith the element 10, thereby substantially doubling its speed of opening. ,This renders it possible to employ the simple form'of sliding disk valveshown, instead ot a valve having multiple radial-ports, as in our said previous application. The improvements hereinlset forth considerably simplify and cheapenthe valve and its operating means. i i
